Part of my image is blurred or out of focus. What should I do?

• Try the following solutions:
  • Adjust the focus.
  • Clean the projector lens.
    
    Note: To avoid condensation on the lens after bringing the projector in from a cold environment, let the projector warm up to room temperature before using it.
  • Position the projector close enough to the screen.
  • Place the projector directly in front of the center of the screen, facing it squarely, if possible.
  • Turn on automatic keystone adjustment in the projector's menu.
    
    Note: Excessive angles or use of keystone correction (vertical and horizontal) can affect image sharpness and quality.
  • Adjust the Sharpness setting to improve image quality.
  • If you are projecting from a computer, press the Auto button on the remote control to automatically adust the tracking and sync. If any bands or overall blurriness remains, display a uniformly patterned image on the screen and manually adjust the Tracking and Sync settings.
